Pixelmon 2.5.2 crash

I'm also having problems loading Pixelmon 2.5.2. Minecraft and Forge both load up fine just not Pixelmon.The install tutorial video shows a 2.3 version, so I'm not quite sure what I'm doing wrong with the 2.5 version.

A detailed walkthrough of the error, its code path and all known details is as follows:

OK so first Off re install Forge and Pixelmon then Drag the Pixelmon Package into the Mods folder inside your .minecraft and all should run smoothly if your still having problems let me know
